<h2>Detailed Description</h2>
<p>The QColumnView class provides a model/view implementation of a column view.</p>
<p>QColumnView displays a model in a number of QListViews, one for each hierarchy in the tree. This is sometimes referred to as a cascading list.</p>
<p>The QColumnView class is one of the <a href="model-view.html">Model/View Classes</a> and is part of Qt's <a href="model-view-programming.html">model/view framework</a>.</p>
<p>QColumnView implements the interfaces defined by the <a href="qabstractitemview.html">QAbstractItemView</a> class to allow it to display data provided by models derived from the <a href="qabstractitemmodel.html">QAbstractItemModel</a> class.</p>

<h2>Property Documentation</h2>
<h3 class="fn"><a name="resizeGripsVisible-prop"></a>resizeGripsVisible : bool</h3>
<p>This property holds the way to specify if the list views gets resize grips or not.</p>
<p>By default, <tt>visible</tt> is set to true</p>
<p>Access functions:</p>
<ul>
<li><div class="fn"/><b>bool resizeGripsVisible () const</b></li>
<li><div class="fn"/><b>void setResizeGripsVisible ( bool <i>visible</i> )</b></li>
</ul>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="QColumnView"></a>QColumnView::QColumnView ( <a href="qwidget.html">QWidget</a> * <i>parent</i> = 0 )</h3>
<p>Constructs a column view with a <i>parent</i> to represent a model's data. Use <a href="qabstractitemview.html#setModel">setModel</a>() to set the model.</p>
<p>See also <a href="qabstractitemmodel.html">QAbstractItemModel</a>.</p>
<h3 class="fn"><a name="dtor.QColumnView"></a>QColumnView::~QColumnView ()</h3>
<p>Destroys the column view.</p>
<h3 class="fn"><a name="columnWidths"></a><a href="qlist.html">QList</a>&lt;int&gt; QColumnView::columnWidths () const</h3>
<p>Returns a list of the width of all the columns in this view.</p>
<p>See also <a href="qcolumnview.html#setColumnWidths">setColumnWidths</a>().</p>
<h3 class="fn"><a name="createColumn"></a><a href="qabstractitemview.html">QAbstractItemView</a> * QColumnView::createColumn ( const <a href="qmodelindex.html">QModelIndex</a> &amp; <i>index</i> )&nbsp;&nbsp;<tt> [virtual protected]</tt></h3>
<p>To use a custom widget for the final column when you select an item overload this function and return a widget. <i>index</i> is the root index that will be assigned to the view.</p>
<p>Return the new view. <a href="qcolumnview.html">QColumnView</a> will automatically take ownership of the widget.</p>
<p>See also <a href="qcolumnview.html#setPreviewWidget">setPreviewWidget</a>().</p>
<h3 class="fn"><a name="previewWidget"></a><a href="qwidget.html">QWidget</a> * QColumnView::previewWidget () const</h3>
<p>Returns the preview widget, or 0 if there is none.</p>
<p>See also <a href="qcolumnview.html#setPreviewWidget">setPreviewWidget</a>() and <a href="qcolumnview.html#updatePreviewWidget">updatePreviewWidget</a>().</p>
<h3 class="fn"><a name="setColumnWidths"></a>void QColumnView::setColumnWidths ( const <a href="qlist.html">QList</a>&lt;int&gt; &amp; <i>list</i> )</h3>
<p>Sets the column widths to the values given in the <i>list</i>. Extra values in the list are kept and used when the columns are created.</p>
<p>If list contains too few values, only width of the rest of the columns will not be modified.</p>
<p>See also <a href="qcolumnview.html#columnWidths">columnWidths</a>() and <a href="qcolumnview.html#createColumn">createColumn</a>().</p>
<h3 class="fn"><a name="setPreviewWidget"></a>void QColumnView::setPreviewWidget ( <a href="qwidget.html">QWidget</a> * <i>widget</i> )</h3>
<p>Sets the preview <i>widget</i>.</p>
<p>The <i>widget</i> becomes a child of the column view, and will be destroyed when the column area is deleted or when a new widget is set.</p>
<p>See also <a href="qcolumnview.html#previewWidget">previewWidget</a>() and <a href="qcolumnview.html#updatePreviewWidget">updatePreviewWidget</a>().</p>
<h3 class="fn"><a name="updatePreviewWidget"></a>void QColumnView::updatePreviewWidget ( const <a href="qmodelindex.html">QModelIndex</a> &amp; <i>index</i> )&nbsp;&nbsp;<tt> [signal]</tt></h3>
<p>This signal is emitted when the preview widget should be updated to provide rich information about <i>index</i></p>
